Tihe `present invention relates to spool carriers for looms used in weaving tuftedi In spoolfabrics, suchas Axminster rugs. carriers of this type and tutt yarns are wound ontwo or more spools carried end to end in bearings-mounted ontav frame barl has for its ob'ect to Tarovido a` device ofv l i simple andstrong construction which 'will firmly support the spools during the movement of the carrier, but which Canby a simple manipulationr be movedto permit the removal ofthe spools.

Other objects and features of novelty will be apparent from the following description taken in connection with the drawings, inwliich,

Fig. 1 is an elevationof a spool carrier mounting three spools, parts being broken away and in section; f

Fig. 2 is-a crosssection on line 2 2 Vof Fig. 1; s

Fig. 3 is an elevational view, partly in 'section' on the line 3--3 of Fig. 2, and

Figs. 4c and are perspective views illustrating the structure for connecting two spools so that they will rotate together.

Referring to the drawings, the beam, or frame, of the device is designated by the numeral 10. It consists of an elongated hollow bar, preferably of metal, .of rectangular form in cross section. This bar, as shown, supports three spools 11, 12 and 13. The outer spindles of the two outer spools 11 and 12 are rotatable in bearings formed in the ends of brackets 14 fixed to bar 10, the bearings opening outwardly and the spindles being retained therein by pivoted latches 15, so that the spindles can be moved transversely out of the brackets when the latches are removed. y

The usual yarn tubes are shown at 16; the devices for holding the carrier on its chain, at 17; and the friction brakes for'` `preventing too rapid rotation of the spools, at 18. The present invention has nothing to do with these parts, so that further reference thereto is unnecessary.

The axial ends, or spindles, of the intermediate spool 13 are mounted respectively in a bearing 19 rigidly secured to beam 10 r and in a bearing 20 pivoted to the beam on a transverse axis; and the contiguous yends of the outer spools are non-rotatably connected to the center spool spindles, whereby the threespools are connected for. rotation together', but the two outer spools may be. withdrawn axially. Any suitable device for thus connecting the spools may be employed.v Thede-vice illustrated in Figs. 31v andv 5 consists of cruciform sockets in the1 axial endsl of the intermediate spool-and correa,

sponding projections on the contiguous-endsv of the two outer spools. f The present invention relates-to the construction of the intermediate bearing` 20.

It will'be observedthat.A this bearing is,l

formed'inthe outer endof an arm 21 which .is normally supported parallel with the other bearings, or at right angles lto, the beam 10. vThis arm lis fulcrumed on a trans- `verse axis so thatl it is capable kof being movedtoth'e dotted line positionshownin F1g.,1., In the specific4 formiof the invention shownarm21 is-.pivoted on-.a pin 22 whiehpasses through thesides of Aan open box 23 and is riveted or otherwise secured to the sides of` beam 10. Box 23 islet into the beam through an opening cut in the wall thereof and tits snugly against the interior walls of said beam, as clearly shown in Fig. 2, the edges of the box at its open side boing tiush with the surface of the beam. The box thus reinforces the beam at this point, so that the beam is not weakened by cutting out the portion thereof necessary to accommodate the box. Arm 20 extends downwardly from its pivot point and terminates in a foot 24 which engages the bottom of the box 23 when arm 21 is at right angles to the beam and thus prevents inward rotationof the arm beyond this position. The arm is yieldingly held from outward rotation by a stout bow spring 25 which has a reduced end 26 engaging a central longitudinal slot 27 formed in the sole of foot 24 and has its other end'also reduced and entered in a slot in box l23. Spring 25 normally holds the foot firmly engaged with the bottom of box 23 with the arm 21 lat-right angles to beam 10 and the bearing in said arm coaxial with the other bearings.

The spools can be removed simply by unlatohing the outer ends of spools 11 and 12 and lwithdrawing" them axiallyV from engagement with spool 13 and then .moving arm 2l against the tension of spring 25 to the dotted line position shown in Fig. l and lifting out spool 18, the axial ends of the latter being free from their bearings in this position of arm S21.

Having thus described the invention,`

what is claimed as new and desired to be secured by LettersPatent is:

l. A spool carrier olf the kind described comprising in combination, a pair of coaxial spools rotatably supported at their non-adjacent ends in bearings rigid with the frame et the carrier, a transversely cxtending two-arm levei| ulcruined to said frame having: a bearing in its outer end .tor the contiguous ends et said spools, the inner end ot' said lever terminating in a foot engagii'lg a surface oit the Vtrarne when the bearingl in said outer end is coaxial with the other bearings, and a spring exerting pressure on said lever tending to hold said foot against saidv surface.

2. A spool carrier ot the kind described comprising in combination a pair ot coaxial spools rotatably supported at their non-adjacent ends in learings rigid with the traine bar of the carrier, a transversely extendingl two-arm lever fiile-ruined to the arrier having a bearing at is outer end lor the contiguous ends of said spools, the inner end ol said lever engaging a surface ot said traine bar at one side of a plane passing through the lulcruin at right angles to the bar, and a spring acting on said lower end and tending to hold it in firm engagement with said surface` 3. A spool carrier of the kind described comprising in combination a hollow bar, two bearings fixed thereto, a portion of the wall of said bar between said bearings being cut away, a box open at one side fitted in said bar, a. two-arm lever fulcrumed in said box having abearing in its outer end, the inner arm of said lever terminating in a foot, and a bow spring engaging said l'oot at one end and said box atrthe other end and normally holding said toot in lirln engagement with said box with the bearing in said lever coaxial with the other bearings.

fl. A spoel carrier of the kind described comprising in combination a hollow bar substantially rectangular in cross section, two bearings lixed thereto, a portion ot the wall of said bar between said bearings being cut away, a substantially rectangular box open at one side secured in said bar with its edges ilush with the surface ol said bar, two-arm lever fulcrumed in said box having a bearing in its outer end, the inner arm ot :raid lever terminating in a foot, a bow spring engaging said 'foot at one end and said box at the other end and normally holding said l'oot in firm engagement with said box with the bearing in said lever eoaxial with the other bearings.
